F.A.A. Approves iPads in Cockpits, but Not for Passengers

The rule barring passengers from using a Kindle, an iPad or even a calculator were originally made to protect the electronics of an aircraft from interference. Yet pilots with iPads will be enclosed in the cockpit just a few inches from critical aviation equipment.

There is some thought that the rule forbidding devices during takeoff and landing was made to ensure that passengers paid attention. The F.A.A. has never claimed this. (If this was the case, passengers would not be allowed to have books, magazines or newspapers during takeoff and landing.)
